gdb: enable -Wmissing-prototypes warning
While compiling with clang, I noticed it didn't catch cases where my function declaration didn't match my function definition. This is normally caught by gcc with -Wmissing-declarations. On clang, this is caught by -Wmissing-prototypes instead. Note that on gcc, -Wmissing-prototypes also exists, but is only valid for C and Objective-C. It gets correctly rejected by the configure script since gcc rejects it with: cc1plus: error: command line option '-Wmissing-prototypes' is valid for C/ObjC but not for C++ -Werror So this warning flag ends up not used for gcc (which is what we want). gdb/ChangeLog: * configure: Re-generate. gdbserver/ChangeLog: * configure: Re-generate. gdbsupport/ChangeLog: * configure: Re-generate. * warning.m4: Enable -Wmissing-prototypes.
